A TTORNEYS walls which terminate in flanges Patented July 4:, 1933 nrren ROY T. AXE, OF SYRACUSE, NT YURI T, ASSIGIIOR, BY IZTESNE ASSTGNI/IENTS, TO THE SYRACUSE TRUST CGZYIPAN YORK, TRUSTEE SYRACUSE, NEVT YORK, A CORPORATION 01 NEW SHEET MTJITAL SASiI-I CQNSTRUCTION Application filed April 3.2, 19%, Serial This invention relates to window constructions, particularly applicable for railway cars, street cars, motor busses, etc. and particularly sheet metal sashes composed of thin sheet metal and has for its object, particularly simple and eflicient wear strip for the thin metal parts or flanges which coact with the window stop.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing, in which like characters designate corresponding parts in all the views.

Figure 1 is afragmentary elevation of a sash embodying my invention.

Figure 2 is a sectional view on line 2-2, Figure 1, the contiguous portion of the window frame being also shown.

Figure 3 is a View similar to Figure 2 showing a compression device coacting with the weather strip.

1 designates the window frame which is provided with inner and outer stops 2, 3, these stops being usually formed up of sheet metal and secured to the window frame proper in any suitable manner. The outer stop 3 is shown as formed integral with the frame 1 and the inner stop 2 as detachable and secured to the frame 1 in any suitable manner as by screws 4. The inner stop is also shown as formed with a. curtain guide 5.

6 designates the sash, the stiles and rails of which are usually formed up of sheet metal.

7 designates the stiles, the body of which is formed of a single piece of thin sheet metal as brass and having front and rear 8 at the edge of the sash, which flanges are opposed to the stops 2, 3. Each stile on its inner side is provided with a suitable channel 9 for receiving the pane of glass 10 and with a removable glazing strip 11. The glazing strip forms no part of this invention.

Also, a suitable corner iron 12 is located in the corner of each stile and rail, this being formed up of sheet metal Ll shape in general outline with the branches of the U No. 268,436. Renewed June 2'7, 1932.

formation extending into internal grooves formed in the body 7 in the front and in the rear of the channel 9 which receives the glass pane 10. The corner iron forms no part of this invention.

The wear strip is formed of sheet metal and shaped to embrace the flanges 8 to stiffen the same and receive the wear due to the movement of the sash along the stops 2, 3. This wear strip has portions 13 and i l overlying the outer faces of the flanges 8 respectively and an intermediate re-entrant portion extending around the free edges of the flanges 8 and having portions overlying the inner opposing faces of said flanges and a yoke portion 14 which connects those portions which engage the inner sides of the flanges 8. The portion of the wear strip which coacts with the outer stop 3 is also formed with an angular flange 15 which extends away from the sash and is located in a position to shield the crevice between the wear strip and the outer stop 3, from the inlet of dust and drafts of air. The wear strip extends to the full length of the sash and laps the ends of the top and bottom rails as shown at 17.

19 is a weather strip of any suitable construction located in the re-entrant portion of the wear strip and secured thereto. The weather strip 19 has a base portion overlying the yoke portion i l of the wear strip and a reversely extended portion 20 for engaging the window frame. The base portion is held in position by a strip 21 overlying it and by screws 22 extending through the strip 21 through the base portion and threading into the yoke portion 14 of the wear strip.

As seen in Figure 3, the inner stop is usually provided with one or more spring pressed comuression devices 23 which thrust the sash to ard the outer stop and this compression device has a head 24 which coacts with tee portion of the wear strip on the inner side of the sash, thrusting the portion of the wear strip on the outer side of the sash against the outer stop 3.

This sash construction is particularly advantageous in that the major part of the sash can be formed of comparatively light sheet metal and the sash stiffened and the port-ions thereof which engage the frame or the stops thereof protected against wear by the wear strip.

Owing to this construction, the sash is particularly light, firm and economical in construction and at the same time, durable in use.

\Vhat I claim is:

l. The combination with a window frame having av window stop, of a sash having a hollow sheet metal member and a wear strip extending lengthwise of said member 011 one side thereof for coacting with the stop, the wear strip having an angular flange extending away from the sash forming a shield for the crevice between the stop and the wear strip.

2. The combination with a window frame having inner and outer stops forming a guide for a sash, and a sash having a hollow metal member formed with front and rear spaced apart flanges extending between the stops, of a wear strip having means fitting and overlying the sides of the flanges opposed to the stops and detachably secured to said flanges, the wear strip terminating bet veen the inner and outer longitudinal edges of the sash. memher on which the wear strip is mounted.

3. The combination with a window frame having inner and outer stops forming a guide for a sash, and a sash having hollow metal member formed with front and rear spaced apart flanges extending between the stops, of

a. wear strip fitting and overlying the sides of the flanges opposed to the stops and detachably secured to said flanges,,the wear strip having outside portions overlying the sides of the flanges opposed to the stops, and an intermediate portion connecting the outside portions, the outside portions terminating between the inner and outer longitudial edges of the sash member on WlIlCl'l the wear strip is mounted. I

4. The combination with a window frame having inner and outer stops forming a guide for a sash, and a sash having a hollow metal member formed with front and rear spaced apart flanges extending between the stops, of a wear strip fitting and overlying the sides of the flanges opposed to the stops and detachably secured to said flanges, the wear strip having outside portions overlying the sides of the flanges opposed to the stops, and an intermediate portion connecting the outside portions, the outside portions terminating between the inner and outer longitudial edges of the sash member on which the wear strip is mounted, said intermediate portion conforming to the flanges, whereby the portion of the intermediate portion overlies and fits the inner faces of the flanges.

5. The combination with a window frame having inner and outer stops forming a sash guide, and a sash comprising a sheet metal member having front and rear flanges opposed respectively to the stops, of a wear strip having portions overlying the outer sides of the flanges, and a re-entrant portion extending between the flanges and engaging the inner opposing sides of the flanges, whereby the wear strip snugly and detachably fits said flanges, said portions which overlie the outer faces of the flanges terminating between the inner and outer longitudinal edges of the sash member on which the wear strip is mounted.

6. The combination with a window frame having inner and outer stops forming a sash guide, and a sash comprising a sheet metal member having front and rear flanges opposed respectively to the stop, of a wear strip having portions overlying the outer faces of the flanges, and a re-entrant portion extending between the flanges and engagin the inner opposing sides of the flanges, said portions snugly and detachably fitting the flanges, whereby the wear strip is removable, and a weather strip located in the re-entrant portion of the wear strip and secured thereto.

7. The combination with a window frame having a window stop, of a sash, and a wear strip extending lengthwise of the edge of the sash for coacting with the stop, the wear strip having an angular flange extending away from the sash forming a shield for the crevice between the stop and the wear strip.

8. The combination with a window frame formed with a sash guide, of a sash movable along the guide and having a sheet metal strip angular 1n cross section and embracing the edge of the sash, said strip being formed with an angularly extending flange extending away from the sash and shielding the crevice between the sash and the guide.

9. The combination with a window frame having inner and outer stops forming a guide for a sash, and the sash extending at its edge between the stops, of a wear strip having means embracing the margin of the sash and overlying the faces thereofopposcd to the stops, the wear strip terminating between:

the inner and outer longitudinal edges of the sash members on which the wear strip is mounted, one of the flanges of the wear strip being formed with an angularly extending lip arranged to shield the crevice between the strip and the opposing stop.

.In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga, and in the State of New'York, this tenth day of April, 1928.
